Security Camera Input Setup

 Security Camera Input Setup

Artificial Intelligence (AI) security cameras are specialized network IP cameras that perform advanced analytical functions such as vehicle detection, person detection, face detection, traffic counting, people counting, and license plate recognition (LPR). These artificial intelligence functions are achieved using highly advanced video analytics software that is built-in to the camera and recorder they are connected to. AI cameras can be used as a stand-alone device by recording to an SD card, or they can be connected to a network video recorder (NVR) to create a multi-camera AI system that records to a central hard drive. Please note that only certain models are capable of license plate recognition / automated number plate recognition (ANPR).

A special characteristic some network video devices possess is an integrated input & output ports. This incorporation allows for the communication and interaction of external devices, such as but not limited to:

1.   Doorbells

2.   Switches

3.   Alarm System Relay

4.   Pressure strips

5.   Detectors (frequency, smoke, movement, sound, temperature, and humidity sensors)

All these functions can be achieved via:
1.   NVR/DVR (remote or local)
2.   Application through a smart device (Tablet or Phone)
3.   Computer (local or remote / software or browser)

 

Camera / DVR / NVR Alarm Input

Motion sensors / motion detectors can be integrated with video surveillance systems to provide additional security for buildings and also outdoor areas. For example, a PIR sensor (passive infrared) can be connected to the alarm input of a security camera DVR or IP camera NVR to trigger video recording and send an alert to the property owner that motion has been detected in a certain area.

When motion is detected by the motion sensor, it triggers the following alarm actions.
1.   Trigger video recording on the camera associated with the alarm.
2.   Enable the alarm output on channel one, where I have an alarm light attached (turn the strobe light on).
3.   Pop-up live video of the camera associated with the alarm on the DVR’s display monitor.

Here are some additional actions that can be triggered from an alarm input.
1.   Capture a still image snapshot.
2.   Send a push notification to the mobile app for iPhone & Android.
3.   Enable the alarm buzzer on the DVR / NVR.
4.   Send an email notification.

The inputs and outputs can be used to eliminate unnecessary recording of video or coincide with your alarm system to systematically create a reliable and accountable security source. When input and output mechanisms are triggered, you can (manually or automatically) request through the network video device that certain actions be performed over the network as well as trigger devices attached to the output ports. Example:

This example picture above shows a person interrupting a sensors function. This creates a signal that travels to the camera and the camera computes the message. The camera then functions as programmed and starts recording (snapshots or footage) to the delegated device while simultaneously triggers a relay to close. When the relay closes, it completes the circuit for the siren or strobe to activate. Another configuration (as long as the cameras capable), have the camera record to the desired method based on motion and simultaneously trigger the relay to set off the siren. In this example, a motion sensor is taken out of the equation.

Again, the above picture shows only one of many configurations. You can configure in whatever method you desire. Including or excluding recording methods based off of:

·        Motion (movement takes place)

·        Masking (the camera has been covered or obstructed significantly)

·        Video Loss (picture is no longer materializing, this feature is more prone to function correctly via a recorder or program)

Other devices that can be attached and configured to your I/O ports are as follows:

Device Type	Description	Occurrence of activation
Entry Contacts	Simple magnetic sensors detecting opening of doors, windows, gates and shutters.	When the circuit is broken (door is opened) the camera can record and/or send a snapshot and notifications
Motion Sensors	A sensor that detects motion either based on heat, light, or frequency	When motion is detected, the sensor breaks the circuit and  the camera can record and/or send a snapshot and notifications
Glass Break or Glass Shock Sensor	A sensor capable of distinguishing the sound/vibration of breaking glass and/or splintering wood.	When glass is  disturbed or shattered, the glass sensor breaks the circuit and the camera can record and/or send a snapshot and notifications
Pressure strip or switch	A pressure or switch sensor that are needed to interact with before gaining entry or exiting a premise or structure	When the sensor is triggered it breaks the circuit and the camera can record and/or send a snapshot and notifications

How-to Install Motion Detectors with a Security Camera System

Installing a motion detector and integrating it with a security camera system is fairly simple. CCTV Camera Pros supports professional and DIY installers. Most PIR motion sensors are 12V DC powered which gives installers the choice of using a individual 12V DC power supply or one of the ports on a multi-channel power supply box (the same ones used with security cameras).

In this first diagram, a single 12V DC power transformer is used. This is how it works.

1.   On the right side of the diagram, the alarm input / output panel of the DVR is shown. This is what the alarm panel on the back.

2.   18/2 gauge power cable connects the output of the motion detector to one of the alarm input ports on the DVR.

3.   18/2 gauge power cable is also used to connect the motion detector to an individual DC power supply.

4.   A PT-4 power lead connects the raw cables to the 3.1mm plug on the power supply.

Installation with Power Supply Box

A multi-channel power supply box can be used instead of an individual power supply.

This installation is the same as the one above using the single power supply. The only difference is the use of a multi-channel power supply box to power the motion detector. CCTV Camera Pros supplies many of these power boxes for security camera installations. These power boxes can be shared with cameras and 12V DC powered alarm sensors. Because power supply boxes use screw based wire terminals, there is no need to use a PT-4 power lead (as with the individual power supply installation). Same connection for Camera & NVR.

Most of Camera PIR motion sensor is located on the front of the camera, just below the camera lens. This motion sensor is designed to detect movement of human sized objects when they come into view of the camera’s lens. The camera has a 2.8-12mm varifocal lens which when adjusted to the widest angle (the 2.8mm setting) the camera provides a 109 degree horizontal field of view. The PIR sensor detects motion across a 100 degree field of view. Please note that if you adjust the lens to a more narrow field of view, this does not effect the area where the PIR sensor will detect motion.

In my experience, using a PIR sensor based motion detection is much more reliable than software based video motion detection (especially for outdoor video surveillance). Typically there are a lot of small moving objects outdoors which makes it difficult to get the sensitivity just right. When security cameras turn to night mode, there is typically some video noise because of the lack of light. This noise can cause false alarms when using video motion detection. A PIR sensor uses infrared light to measure the radiation reflected by objects in its view. When a certain amount of this radiation changes, the PIR sensor triggers an alarm, so they are not susceptible to some of the challenges of outdoor video motion detection.

FAQ

Here are some frequently asked questions about integrating PIR motion detectors with security camera systems.

·        How are motion detectors used with security camera systems?
The most common way to integrate a motion detector with a security camera system is to hard wire the motion detector to the same surveillance DVR that your security cameras are connected to. You must make sure that your DVR that has alarm inputs.

·        Can I just use motion detected from my security camera instead of an external motion sensor?
Yes, most DVRs support video motion detection triggered by cameras. Please note that this is different from PIR (passive infrared) motion detection and can be less reliable. Video motion detection tends to produce more false positives than PIR motion detection, especially in outdoor and infrared camera applications. This is because the video tends to be more noisy and outdoor environments tend to always have some motion from wind and other natural elements.

·        What type of cable is used to wire motion detectors to DVRs?
The following types of cable can be used to wire motion detectors: CAT-5 cable (one pair), 18/2 conductor power cable.

·        Do motion detectors require power?
Yes. Most PIR motion detectors use 12V DC power. All of ours include the proper power supply with them.

·        Can I use multiple motion detectors with my surveillance system?
Yes, as long as your DVR has multiple alarm input ports, you can use multiple motion detectors. Different model DVRs support different numbers of alarm inputs so consult the specification or contact us if you need help.

Not every camera or NVR/DVR possesses this unique features or can be operated through the above mentioned methods. Be sure you research everything you will need to make this type of setup successfully work for you. This includes the correct relays, power supplies, capable camera and recording devices. Most our IP mega pixel cameras and recorders have the capability of all previous mention features above.

AI Based Camera Output Triggers Strobe Light

AI Based Camera Output Triggers Strobe Light 

Artificial Intelligence (AI) security cameras are specialized network IP cameras that perform advanced analytical functions such as vehicle detection, person detection, face detection, traffic counting, people counting, and license plate recognition (LPR). These artificial intelligence functions are achieved using highly advanced video analytics software that is built-in to the camera and recorder they are connected to. AI cameras can be used as a stand-alone device by recording to an SD card, or they can be connected to a network video recorder (NVR) to create a multi-camera AI system that records to a central hard drive. Please note that only certain models are capable of license plate recognition / automated number plate recognition (ANPR).

 

DVR / NVR Alarm Relay Output

Please note that the the alarm strobe light is self-powered. The alarm outputs on the DVR / NVR are simple relays (they are either open or closed). They DO NOT provide any power output. Also, please note that you can ONLY connect low voltage devices alarm devices to these alarm relay ports. Connecting high powered devices can fry your motherboard and ruin your DVR / NVR.

Important WARNING! The maximum current rating of these alarm relays is 1A, the voltage is 30VDC/ 250VAC, so the maximum power rating is 30W for DC alarm device, 250W for AC alarm device.

You can see above how I wired the strobe light to the output port. Notice how the strobe light’s 12V DC power supply is connected in-line. I used 18 gauge 2 conductor PVC Insulation Jacket Unsheilded / Stranded Copper wire to connect the strobe light to the recorder.

Here is a close-up of the alarm output ports on the back of the DVR / NVR. I am using the COM1 and NO1 ports. NO stands for normally open, which means that power does not flow thorough the relay until the alarm is triggered.

AI Software Setup

Please follow these steps to configure the AI software on the NVR.

From the DVR/ NVR main menu, select AI / Event.

On the AI / Event screen, do the following.

1.   Select More from the AI Event menu.

2.   Select the camera that you are applying the AI rule to from the camera dropdown.

3.   Select Line Crossing as the event type.

Next, do the following.

1.   Check the Enable Detection by IPC (IP Camera) checkbox.

2.   Check the Draw Line checkbox and draw your tripwire on the screen.

3.   Choose the direction of the traffic flow used to trigger the alarm. You can choose a single direction or both directions.

Next.

1.   Click on the Detection Target tab.

2.   Check Human for the detection target type. Uncheck Motor Vehicle and Non-motor Vehicle as they are not applicable in this case.

1.   Click on the Trigger Mode tab.

2.   Click on the Alarm Out Configure button. Please note that you may setup additional alarm triggers on this screen such as image snapshot, mobile app push notification, alarm buzzer, pop-up video, and email alerts.

On the DVR alarm output screen, select the alarm output that your light (or other device) is connected to from the window on the left and click on the arrows (>>) to put the alarm output on the right window. Then, check the checkbox next to it.

Click OK. Then, click Apply in the lower right.

You may then close all of the DVR / NVR configurations screens and return to the live view of your security cameras.

AI Software / Object Detection Visualization

On the live security camera view of your recorder, double click on the camera that you are using for this alarm project to show that camera’s live view full screen. You can enable the AI / Object Visualizations by clicking on the above icon.

 

When you enable the AI software visualizations on the live camera view, a few things happen.

1.   The alarm event window opens on the right. When your security camera detects the event that you configured, a snapshot image will appear in that screen to document the event.

2.   All objects that the system is able to detect will be outlined. Please note above that I am outlined with that yellow box because the AI software is detecting me as a human. The cars in the background are outlined in purple. Even though we are only using people detection for our alarm, the NVR software still outlines the other object types that it recognizes.

3.   The line crossing / virtual trip wire is shows in red. And the A->B traffic flow that I setup it also shown

4.   NVR / DVR Alarm Output Turns Light On

Last, here is a screenshot of the strobe light turned on as a result of the human detection / line crossing event.

Video Wall Magic

Video Wall Magic 

Whenever people talk about CCTV, one of the first associations is video walls. No matter how powerful the servers behind, it is the visual that produces the "wow" effect — even on the most tech-savvy customers. Yet, they often back off, having heard the price. And this is where all EVO Global customers clearly benefit: EVO video wall has just got a major enhancement, and it does not cost you a rupee. EVO by LUXRIOT.

Video walls are widely used everywhere from airports to rock concerts. Traditionally, in CCTV their application includes, but is not limited to, showrooms and control centres. To build a video wall, you take narrow bezel monitors, projectors, or TV sets, and tile them together. Depending on the goal, some or all of them may form one huge screen. This resulting "transformer" display is much better rather than just one large display: it offers customizable shape and size, distributed processing, and superior reliability.

Typically, you would employ additional technologies to make several output devices work as one. EVO Global allows casting a single picture onto a combination of displays from separate workstations. Most importantly: without anything other than just regular Windows display management. EVO is one of the most comprehensive enterprise-level VMS solutions on the market, featuring interactive maps linked to alarms; an advanced event and action manager; analytics tools; video wall support and other components you will definitely appreciate. To ensure the safety of your data, the software also offers edge recording for synchronising all data with IP devices storage, archive replication, advanced system health monitoring and failover, which will reduce the disruption of your video surveillance recordings to zero. SSA Integrate is India Regions business partner.

Fantastic Flexibility

Video walls have been available in EVO Global since its very first versions. So what's different now?

Earlier, we already saw how the Luxriot virtual video wall helps organize collections of displays, including those in different locations. Now, EVO Global offers another option: mosaic display, or, according to a customer, "the real video wall". Previously, you could have a virtual collection of screens, scattered across the place, managed from your office. From now on, EVO Global also gives you an opportunity to combine several local screens into one. Both approaches fit into the video wall definition, yet they have different use case scenarios. And, both retain EVO's convenient and flexible management instruments.

In other words, EVO now acts as your video wall controller — no middleware required. The displays may be independent, maybe even driven by different workstations. But, in EVO they behave as a single canvas. Clever algorithms ensure full synchronization between the screens, guaranteeing zero delays.

Such architecture provides notable flexibility. Not only can you re-arrange the displays or add new ones at any point, but you also are free to use variegated hardware. This is true for both workstations and display brands. While a consistent video wall solution looks best on homogenous LCD/LED panel sets, a temporary replacement or a quick demo set-up becomes a piece of cake.

As you would expect, the rest of EVO Global video wall functionality remains the same. Once configured, any video wall screen contents can be controlled from anywhere in the universe.

Smooth Setup

Let's consider a use case. 

Four display panels tiled contiguously, driven by two workstations. The task for EVO will be to display one high-resolution picture using all four screens. Simultaneously, an extra display in the operator's room should preview the same layout.

Briefly, the plan is: create a video wall, install clients, assign client displays to the video wall screens.

Add a single screen video wall in EVO Console

Detailed description

Step 1: in your EVO Console, add a new video wall. For the current setup, the wall layout will be simply one screen, 1x1 grid. We shall use the same video wall screen for both the showroom and the operator's room.

Step 2: install EVO Monitor on all client workstations. The client application does not require a license, and you can use either 32- or 64-bit packages. Each application instance may have one or several windows. Therefore, the four panels can be split between two, three, or four workstations. Let's assume we have two client PCs here, each driving two displays.

Step 3: link physical displays to video wall screens. In this case, we have only got a single video wall screen, and we shall use it twice.

First, in the showroom, all 2x2 displays will belong to the video wall screen with a "tiled" option. To do this, open the multi-display settings, select a window, tick the Video wall screen setting, then also tick the Tiled display option on the right. In the mosaic preview, enter the grid size and then select the part of the big screen that is occupied by the underlying physical display.

Second, in the operator's room, simply point the monitor to the same video wall screen, without selecting the "tiled" setting. As a result, the same output will be produced on a single preview display.

Create a tiled video wall in EVO Monitor via multi-display setup

Step 4: have fun managing the video wall remotely or with E&A. For manual remote administration, there is a separate tab in the EVO Monitor application called — who would have thought? — Video wall. To start, drag and drop your video wall from the Resources section on the left. And then, place the desired layouts, channels and maps onto the preview area below. All adjustments will take instant effect and you will notice the changes in both rooms. Don't forget to save the current layout as start-up by clicking the "three stripes" button in the upper right corner of the preview area.

Tips & Tricks

To make the most out of the tiled video wall, remember a few aspects:

• make sure the video cards meet the hardware requirements for EVO Monitor
• calibrate your displays to match the brightness and color settings
• use displays with the same aspect ratio and resolution
• choose displays with the near-zero bezel (frame) and minimize the gap between them
